Diamond Star DA40

Diamond DA40 NG

The DA40 NG is a modern, composite four-seater that has become a staple in both high-end flight schools and the owner-flown market. Unlike the earlier Lycoming-powered ‘Star’ models, the NG features the Austro AE300 diesel engine, allowing it to sip Jet-A fuel with remarkable efficiency. Its glider-heritage wings and bubble canopy provide industry-leading visibility and exceptionally docile stall characteristics, making it one of the safest platforms in General Aviation.

Key Features for GA Buyers

• Fuel Efficiency: Burns as little as 5.1 gallons of Jet-A per hour at economy cruise.
• Modern Avionics: Typically equipped with the Garmin G1000 NXi suite and GFC 700 autopilot.
• FADEC Simplicity: Single-lever power control reduces pilot workload and protects the engine.
• Safety Record: Boasts one of the lowest fatal accident rates in the industry thanks to its ‘fail-safe’ composite airframe and stable handling.

Trade-offs

• Payload Constraints: With a full 39-gallon fuel load, the remaining payload for passengers and baggage can be tight for four adults.
• Climb Performance: While steady, the climb rate (690 fpm) is more modest compared to high-performance competitors or the Lycoming-powered XLT variant at lower altitudes.
• Ingress/Egress: The ‘bathtub’ style entry requires stepping over the side, which may be challenging for some passengers.
